凡发热三日之后。其痘先出于面之下部，在两颐者为上，在两颊者为中。若额际
先发者，系毒参阳位，为下下矣。凡晓星报点稠密者，虽各部稀疏难治。如晓星报点稀
疏光润者，虽各部稠密，必有可治之机焉。然五脏之精华，皆上注于头面。故五脏之精
华充足者，则痘点虽多，必能窠粒分明，高耸润泽，虽多无害；若精华不足，则邪毒用
事，奔溃成片，如 如麸，而为不救之症矣。

干兑属金，肺之象也，受克于南离之心火，得生于坤良之脾土。坎属水，肾之象，
受克于坤艮之脾土，得生于干兑之肺金。坤良属土，脾之象，受克于震巽之肝木，得生
于南离之心火。震巽属木，肝之象，受克于干兑之肺金，得生于坎之肾水，离属火，心
之象，受克于坎之肾水，得生于震巽之肝木。
夫干兑属金，金能克木，木既受克，则衰而不能生火，故金不受其克，以此断言为
吉。夫震巽本俱属木，何巽重而震轻也？盖巽近离火，火生土，土克肾水，而元神竭
矣。故先见此部为凶。如离宫先见标痘者，则火亢水必害，不害则火必反逆乘，故为险
症，惟若痘见滋润有神，则水火交会，虽凶为吉。如离宫先出，坎宫后出，而坎宫痘反
光泽，离宫痘反惨暗者，是南离心火，为坎中肾水所胜而克矣。然釜下而无火，则物安
能得熟耶？故必不能成浆而死，是以为凶，其余可仿类推，宜再兼以各部痘粒疏密，颜
色之如何，以决之，万元不中者也。
凡是发热三天之后，痘疹首先出现在面部下部，在两腮（颐）部位出现的属于上等，在两颊部位出现的属于中等。如果首先在额头部位出现的，是因为毒邪侵犯阳位，属于下等中的下等。凡是像晓星一样报出的痘点稠密者，虽然其他部位稀疏也难以治疗。如果像晓星一样报出的痘点稀疏且光泽润泽者，虽然其他部位稠密，也一定有可治的生机。然而五脏的精华，都上注于头面。所以五脏精华充足的人，痘点虽然多，一定能颗粒分明，高耸且润泽，即使多也没有危害；如果精华不足，那么邪毒就会肆虐，溃散成片，像麸皮一样，成为无法救治的病症了。

乾、兑属金，是肺的象征，受南方离卦心火的克制，得生于西南坤卦、东北艮卦脾土的生助。坎属水，是肾的象征，受西南坤卦、东北艮卦脾土的克制，得生于西北乾卦、西方兑卦肺金的生助。坤、艮属土，是脾的象征，受东方震卦、东南巽卦肝木的克制，得生于南方离卦心火的生助。震、巽属木，是肝的象征，受西北乾卦、西方兑卦肺金的克制，得生于北方坎卦肾水的生助。离属火，是心的象征，受北方坎卦肾水的克制，得生于东方震卦、东南巽卦肝木的生助。
乾、兑属金，金能克木，木既然受到克制，就会衰弱而不能生火，因此金不受木的反克，据此判断为吉兆。震、巽本来都属木，为什么巽卦重而震卦轻呢？因为巽卦靠近离火，火生土，土克制肾水，导致元神枯竭。所以先见到这个部位的痘疹为凶兆。如果在离宫先出现标痘（痘疹初起），那么火亢盛则水必然受害，如果不受害，火就会反过来逆乘，所以是险症，只有如果痘疹见滋润且有神气，则是水火交会，虽然是凶转为吉。如果离宫先出痘，坎宫后出痘，而坎宫的痘反而光泽，离宫的痘反而惨暗，这是南离心火被坎中肾水所胜和克制。然而锅底下没有火，东西怎么能煮熟呢？所以一定不能化脓结痂而死，这就是凶兆，其余情况可以仿照此类推，应当再结合各部位痘粒的疏密、颜色的如何，来决断，万无一失。
After fever has persisted for three days, if the smallpox lesions first appear in the lower part of the face, those appearing on both cheeks (Yi) are considered superior, while those on both malar regions are considered medium. If they first appear on the forehead, it indicates that the pathogenic toxin has invaded the Yang region, which is classified as inferior-inferior. When the lesions resemble morning stars and are dense, even if other areas are sparse, it is difficult to treat. Conversely, when the lesions resembling morning stars are sparse, smooth, and lustrous, even if other areas are dense, there is a chance for recovery. The essence of the five Zang organs flows upward to the head and face. Therefore, when the essence of the five Zang organs is sufficient, although there may be many lesions, they will clearly form distinct pustules, standing high and moist; thus, their abundance causes no harm. If the essence is insufficient, the pathogenic toxin dominates, causing溃散 (disintegration) into patches like bran, resulting in an incurable condition.

Qian (Heaven) and Dui (Lake) belong to Metal, representing the Lung (Fei). They are controlled by the Heart Fire (Xin Huo) of the South Li (Fire) trigram, and are nourished by the Spleen Earth (Pi Tu) of the Southwest Kun (Earth) and Northeast Gen (Mountain) trigrams. Kan (Water) belongs to Water, representing the Kidney (Shen). It is controlled by the Spleen Earth (Pi Tu) of the Southwest Kun and Northeast Gen trigrams, and is nourished by the Lung Metal (Fei Jin) of the Northwest Qian and West Dui trigrams. Kun (Earth) and Gen (Mountain) belong to Earth, representing the Spleen (Pi). They are controlled by the Liver Wood (Gan Mu) of the East Zhen (Thunder) and Southeast Xun (Wind) trigrams, and are nourished by the Heart Fire (Xin Huo) of the South Li trigram. Zhen (Thunder) and Xun (Wind) belong to Wood, representing the Liver (Gan). They are controlled by the Lung Metal (Fei Jin) of the Northwest Qian and West Dui trigrams, and are nourished by the Kidney Water (Shen Shui) of the North Kan trigram. Li (Fire) belongs to Fire, representing the Heart (Xin). It is controlled by the Kidney Water (Shen Shui) of the North Kan trigram, and is nourished by the Liver Wood (Gan Mu) of the East Zhen and Southeast Xun trigrams.
Since Qian and Dui belong to Metal, Metal controls Wood. Since Wood is controlled, it becomes weak and cannot generate Fire; therefore, Metal is not counter-controlled by Wood, which predicts a favorable outcome. Both Zhen and Xun belong to Wood, but why is Xun heavier and Zhen lighter? This is because Xun is close to Li Fire. Fire generates Earth, and Earth controls Kidney Water, leading to the exhaustion of the Primordial Spirit (Yuan Shen). Thus, seeing lesions in this area first is ominous. If lesions first appear in the Li Palace, excessive Fire will inevitably damage Water; if not damaged, Fire will reverse and attack upwards, making it a critical condition. However, if the lesions appear moist and spirited, indicating the intersection of Water and Fire, the omen turns from bad to good. If lesions first appear in the Li Palace and later in the Kan Palace, but the Kan Palace lesions are lustrous while the Li Palace lesions are dull, this indicates that the Heart Fire of the South is overcome and controlled by the Kidney Water of the Kan center. Without fire under the cauldron, how can the contents cook? Therefore, the pus cannot mature, leading to death, which is ominous. Other cases can be inferred by analogy. One should also consider the density of lesions in various areas and their color to make a judgment, ensuring accuracy.
